According to the announcement of the State Intellectual Property Office, SinOMA Technology Co., Ltd. applied for a project entitled "a low-pressure glue injection device suitable for pultrusion process", the public number CN117799193A, the application date is December 2023.
According to the announcement of the State Intellectual Property Office, SinOMA Technology Co., Ltd. applied for a project entitled "a low-pressure glue injection device suitable for pultrusion process", the public number CN117799193A, the application date is December 2023.
According to the patent abstract, the invention relates to the field of pultrusion molding equipment of composite materials, in particular to a low-pressure gluing device suitable for pultrusion process, including a reflux groove, the upper interval of the reflux groove is provided with a closed low-pressure gluing module and a long cold mold, a cold mold and a spinning separation mechanism are provided on one side of the closed low-pressure gluing module, and a heating mold is provided on one side of the long cold mold;
Among them, the closed low-pressure glue injection module comprises a box, the box is provided with a transverse channel, the opposite sides of the box are respectively provided with an inlet and an outlet, the top of the box is provided with a glue injection port, the glue injection port is communicated with the glue storage tank through the hose road, the hose road is communicated with a return pump; The bottom of the reflux tank is connected with the reflux pump through an outlet hose.
The invention provides a low pressure gluing device suitable for pultrusion process. By sealing the dipping mode of low pressure gluing, the problems of fiber yarn grinding and lint, poor infiltration and fiber tension inequality can be improved, and the product performance can be improved. Through the design of reflux tank, improve the utilization rate of raw materials and reduce the cost of raw materials.
